Calibration Service

Instruments made by others

We understand the convenience of having all the instruments in your laboratory calibrated by a single company. We are therefore able to calibrate many instruments not manufactured by ourselves.¬†Please provide details of what you have and we will advise what we can do. We never compromise the integrity of our calibration services. If we don’t have the expertise, we will tell you!
